作者 于敏 葛盛芳 《安徽科技》 2002年第3期43-43,共1页
在家禽育种工作中应用遗传标记的方法,对某些生化指标进行遗传分析,可以用于早期或间接选择,以缩短世代间隔,加速遗传进展,提高育种工作效率,克服限性性状和某些活体难以测定的性状.对蛋禽进行生化遗传标记育种主要包括以下几种方式:

Foxtail millet (Setaria italica L. Beauv.), as a significant food and fodder cereal crop, was widely cultivated in the Yellow River Valley and is still a kind of farming tradition of millet in Northern China. With the development of agriculture and the improvement of people's living standards, foxtail millet's planting area has be- come less and less in arid and semi-arid region now. However, because of its small diploid genome (1C genome size=420 Mb) and self-pollination, foxtail millet is very suitable for whole genome sequence and is used as an experimental model plant for C4 photosynthesis and biofuel research. In 2012, the completed genome sequence of foxtail millet had been successfully produced by the Beijing Genomics Institute (BGI) and US Department of Energy Joint Genomic Institute (JGI), respec- tively. It will be used as an experimental crop to explore many aspects of plant ar- chitecture, physiology and biochemistry, comparative and functional genomics studies in the bioenergy grasses. To systematically understand the recent research progress in foxtail millet; we summarize the following aspects in this study: germplasm, tradi- tional breeding, physiology and biochemistry, molecular marker, construction of genet- ic linkage map, gene localization, genome sequencing and comparative genome. This may be a door to open for the further development of foxtail millet in the future. 展开更多

This article contributes to research on how climate change will impact crops in China by moving from ex-post empirical analysis to forecasting. We construct a multiple regression model, using agricultural observations and meteorological simulations by GCMs, to simulate the possible planting boundaries and suitable planting re- gions of spring wheat under RCP4.5 scenario for the base period 2040s and 2070s. We find that the south bound- ary of possible planting region for spring wheat spreads along the belt: south Shandong-north Jiangsu-north Anhui-central Henan-north Hubei-southeast Sichuan-north Yunnan provinces, and will likely move northward under RCP4.5 scenario in 2040s and 2070s, resulting in the decrease of possible planting area in China. Moreover, the sowing and harvest date of spring wheat in the base period shows a gradually delayed phenomenon from the belt: south Xinjiang - Gansu, to the Tibet Plateau. As a result, the growth period of spring wheat in China will shorten because of the impacts of climate change. These results imply that a variety of adaptations measures should be set up in response to changing climatic conditions, including developing the planting base for spring wheat, restricting the planting area of spring wheat in sub-suitable areas at risk while expanding the planting area of optimal crops. 展开更多

Distant hybridization refers to crosses between two different species or higher-ranking taxa that enables interspecific genome transfer and leads to changes in phenotypes and genotypes of the resulting progeny.If progeny derived from distant hybridization are bisexual and fertile,they can form a hybrid lineage through self-mating,with major implications for evolutionary biology,genetics,and breeding.Here,we review and summarize the published literature,and present our results on fish distant hybridization.Relevant problems involving distant hybridization between orders,families,subfamilies,genera,and species of animals are introduced and discussed,with an additional focus on fish distant hybrid lineages,genetic variation,patterns,and applications.Our review serves as a useful reference for evolutionary biology research and animal genetic breeding. 展开更多
